It's my preferred cabin when traveling J in that type. It has a more exclusive feel than further back in the bus. From memory, row 12A does not have a window, so avoid that row if you like an outside perspective.

The only 'drawback' to that cabin is that it is immediately behind first. Therefore, you may get a glimpse of the larger serve of lobster, complete with the accompanying goblet of Krug, that you will be missing out in partaking!
